When running zmtrainsa on a mailbox (zmtrainsa username spam junk), the process hangs after it says that the dspam training has started. Like the user in the post I linked above, I also had the "no such feature" problem, and that went away after applying the fixes suggested in the post, but only to cause this to hang.

I am suspicious that the DSPAM training is working at all, based on the DSPAM results I am getting on several of the spam message headers, at least for one specific user. I am also curious if there is a way to reset the DSPAM learning for a particular user, since I have read that DSPAM learns on a per user basis (but that could be a different thread to post).
